Abstract
H and D [Hurter and Driffield] curves were obtained for various film/screen combinations exposed to 60Co, 4-MV and 45-MV photons. Contrast apparently was enhanced more by light-emitting screens than by Pb screens or direct exposure. Flexible film cassettes were more comfortable for the patient and extra-large film can be used for larger patients.This publication has 0 references indexed in Scilit:
